Question

99 Oldsmobile Bravada with 126,000 miles. Service AWD light is on. What could it be and how easy is it to fix?

truck runs and drives great no noise when turning like you hear about in the transfer case just awd service light is on and it doesn't seem to be going into 4wheel at all so could it jst be a sensor or could it be worse the light just came on one day while going down the road on dry pavement.

Usually, it is just the actuator on the transfer case that is malfunctioning. This is not an expensive fix. You should go to your mechanic or local auto parts store and have them hook up an OBDII scanner to the car and check for any fault codes. Many auto parts stores will do this for free. This will tell you if any specific parts, sensors or modules are malfunctioning and need repair or replacement.It will save you hundreds of $$$ if you know what is wrong before replacing a lot of expensive parts. If you need help with the codes and what they mean, just come back here and we will try our best to help. Good luck and let us know if you have any follow up questions!
